Brush chipper

A brush chipper in combination with a trailer and a power supply, said brush chipper comprising a housing carried on said trailer and including an inlet opening and an outlet opening in communication with a discharge chute;

• a cutter bar rigidly carried in said housing intermediate said inlet and outlet openings and a rotor carried on a shaft extending through the end walls of said housing, one end of said shaft being driven by said power source for rotating said rotor;
• cutting blades carried in recesses formed on said rotor, said cutting blades cooperating with said cutter bar when said rotor is being rotated for cutting brush fed through said inlet opening into chips, said recesses including an unoccupied portion for hurling said chips through said outlet opening into said discharge chute;
• blower means including an impeller mounted on the other end of said shaft and conduit means communicating with said impeller and the interior of said discharge chute at a point spaced from said rotor, rotation of said impeller providing a stream of air through said discharge chute for conveying said chips;
• a flywheel mounted on said shaft whereby said power supply can drive said rotor such that the speed of said cutting blades can be reduced from a range of about 9,000 fpm to about 9,500 fpm to a range of about 5,500 fpm to about 7,500 fpm and still provide sufficient force to allow adequate cutting of said brush;
• and air inlet means formed in said discharge chute between said conduit means and said rotor.
